Gap Trade Buy/Sell Indicator for ThinkorSwim

[isaacramsay]

Found this strat and gave it a go at scripting it. It's not perfect, but it works. Please let me know what you guys see, I'd love feedback and to fix any errors.

Gap Trade Buy:

• Setup- today's open is less than yesterday's low
• Trigger- today's price action crosses above yesterday's low + penetration amount(yesterday's range*.05)

Gap Trade Sell:

• Setup- today's open is greater than yesterday's high
• Trigger- today's price action crosses below yesterday's high - penetration amount(yesterday's range*.05)

It is only meant for daily charts so that's where the arrows show up. When a gap trade is set up, a label will pop up top left corner, green if gap buy, red if gap sell. On the minute charts, a line will show up at the penetration amount. When the PA is being crossed, there is an alert, because why not.

Kinda like the Larry Williams Oops strategy. Thanks
